9.32 A uniform rod of mass M and length Lis placed like a ladder against a frictionless wall and fric- ionless horizontal floor. It is released from rest, making an angle 0 with the vertical. Show that tie initial reaction of the wall and the floor are (use only one variable to describe motion) Ry = mg cos a sin a, R; = mg(1 – sin? a) 2 %3D and that the angle at which the rod will leave the wall is cos-'G cos a). 9.32 A uniform rod of mass M and length Lis placed like a ladder against a frictionless wall and fric- ionless horizontal floor.
